Question
Calculate the amount of energy that will be available to big fish in the following food chain, if 10,000 J of energy is available to small algae from the sun :
Small algae → Zooplankton → Fish → Big fish
Solution
The amount of energy available to big fish will be 0.1 J. Given 10,000 J of energy is available to small algae from the sun. It can be calculated as follows:
| Small algae → | Zooplankton → | Fish → | Big fish |
| 10,000 J → | 1,000 J → | 100 J → | 10 J → |
The amount of energy available to big fish is 10 J.
